8 Claims.

My invention relates to improvements in terrestrial globes and has for one of its objects the provision of a globe and globe support by which the globe may be illuminated from the interior by suitable electric or otherlamp.

Another object of my invention is to provide a support for the globe by which it may not only be illuminated from the interior but also on which it may be readily rotatable.

For the purpose of disclosing my invention I have illustrated an embodiment thereof in the accompanying drawing, in which: 7

Fig. 1 is a partial diametrical section of the globe embodying my invention;

Fig. 2 is a transverse section;

Fig. 3 is a plan view of a modified form of a bearing for the globe; and

Fig. l is a plan view of a further modification thereof.

In the embodiment illustrated, I provide a sup porting base I which may be of hollow stamped sheet metal and on which is mounted an arm 2 preferably hollow and secured to the base by means of a suitable stud 3 and clamping nut 4. This arm 2 at its outer end is provided with a vertically extending threaded projection 5 inclined at the proper angle and having an annular shoulder 6 formed thereon, the upper end of the projection being threaded as at i. A supporting disc 8 is mounted on the projection, resting on the annular shoulder 6 and a standard candle type electric lamp socket 9 is threaded on the end of the projection, clamping the disc between it and The socket may be wired through the base i and a suitable control switch It if desired. The standard lamp socket has the usual insulating sleeve H surrounding the live parts thereof.

The globe l2 preferably comprises two semispheres formed of paper preferably treated to render the same translucent or semi-transparent, each having the maps printed thereon. These semi-spheres are connected to an equatorial base ring I3 which is preferably formed of a series of laminated paper rings glued or otherwise secured together to produce the desired thickness. This ring is arranged within the globe and at the meeting edge of the two semi-spheres, not only forming a brace and joining member for the globe proper but also providing a means to which one of the bearing members for the globe may be attached. The southern semi-sphere of the globe has an opening formed therein of sufficient diameter to receive the lamp socket 9 and the walls of this opening are reinforced by a suitable metal grommet I4.

The globe is adapted to fit over the lamp socket andv be supported on the supporting disc 8, the insulating sleeve H of the socket forming one bearing point or pivot member on which the globe may rotate. The second bearing point for the globe comprisesa suitable ring 15 which is connected to the inner ends of a series of radially extending supporting arms or braces I6 which at their outer ends are passed through and bent over the equatorial brace ring l3 as at IT. The socket is adapted to receive a lamp I8 of the candle type and it will be noted that when the globe is. slipped on to the socket the ring l5 will embrace the lamp at a point approximately midway between its top and bottom, thereby forming a bearing point for the globe at a point spaced apart from the bearing point on the lamp socket so that the globe will not tilt. Due to the fact;-

that the bearing ring l5 and its suppdrting arm it are fastened in the equatorial base ring !3 which, as has been noted, is comparatively thick and therefore necessarily forms a shadow on the exterior of the globe when the lamp is illuminated, H

no additional shadow is cast by the upper bearing ring or member.

In the structure illustrated in Fig. 3, the upper bearing ring is formed by a series of wires l9, preferably three in number and connected at their outer ends to the equatorial base ring at equally spaced points so that they cross one another to provide a centrally located receiving socket 2!! for the lamp I9.

In the structure illustrated in Fig. 4 I have shown still another modification wherein the Wires !9' are mounted in substantially the same manner as illustrated in Fig. 3 but in this instance comprise coiled springs to permit the wires to be more readily spread to receive the lamp when it is mounted in position.

I claim as my invention:

1. The combination with a lamp socket and a lamp mounted therein, of a translucent terrestrial globe having an opening therein to receive said ing point on which said globe may rotate, an

annular ring secured to said globe at substantially the equator thereof, and a plurality of wires each having at least one end connected into said ring, said wires extending towards the center of said ring and supporting a lamp embracing portion to provide a second bearing point for the globe.

3. The combination with a lamp socket and a lamp mounted in said socket, of a translucent terrestrial globe having an opening therein to reterrestrial globe having an opening therein to receive said socket, said socket forming one bearing point on which said globe may rotate, an

- annular ring secured to said globe at substantially the equator thereof, and resilient members each having at least'one end connected into said ring and extending towards the center thereof and supporting a lamp embracing portion, said means providing a second bearing point for the globe.

5. The combinationwith a lamp socket and a lamp mounted in said socket, an annular supporting disc carried by said socket, of a translucent terrestrial globe having an opening therein to receive said socket supported on said disc and said socket forming a bearing point for said globe, an annular ring mounted Within and. secured to said globe at substantially the equator thereof, and lamp-embracing means carried by said ring arm, a lamp socket secured to said arm and proand providing an additional bearing point for said globe.

6. The combination with a lamp socket and a lamp mounted therein, of a translucent terrestrial globe formed in two sections, and an equatorial base ring to which said sections are connected, said globe having an opening therein to'receive said socket and said socket providing a beari g point for the globe, and means secured to said equatorial base ring embracing the lamp and providing a second' bearing point forthe globe.

7. The combination with a base, of an arm extending from said base, a disc supportedon said arm, a lamp socket extending upwardly 1 s from said arm above said disc, an insulating sleeve surrounding said lamp socket and a lamp mounted in said socket, a translucent terrestrial globe having an opening therein adapted to receive said lamp socket, said globe being adapted to rest on said disc and having a rotatable bearing on said sleeve, an equatorial base ring mounted Within and secured to said globe and lamp embracing means secured to and supported by said equatorial ring whereby said globe will have two spaced apart bearing points therefor.

8. The combination with a base, of a transversely extending arm supported by said base, a supporting disc secured tothe free end'of said jecting upwardly and above said base, anjinsulating sleeve surrounding said lamp socket, a translucent terrestrial globe having an opening therein, the walls of said opening being protected by a metal grommet, said opening being adapted to receive said lampsocket and the globe being adapted to rest on said disc, an equatorial base ring mounted within and secured to .said globe and lamp embracing means secured to and supported by said base ring whereby said globe 40 will have a pair of spaced apart bearing points.
